History:
(Spider-Woman II#2 (fb)) - Val Cooper, acting head of the
Commission, organized a top scientific team--Dr. Carter Napier,
Dr. Sylvie Yacqua, Hashi Noto-- to try to create a new breed of
super-heroes that would serve the government. Based on Yacqua's
recommendation of the drugs found in the plants in the Amazon
jungle, Yacqua and Noto were dispatched there, led by the guides,
Walter & Elizabeth Cornwall, they gathered a number of
chemicals designed to give a subject spider-like powers. Seeking
a physically fit and loyal test subject, Cooper recommended Julia
Carpenter, an old college associate of hers, as well as the
daughter of the Cornwalls. Cooper convinced Carpenter to come
work for her, and the scientists transformed her into Spider-Woman.

(Spider-Woman II#2 (fb)) - After Spider-Woman
left the government service, the Manipulator secretly met with
Yacqua, Noto, and the maintenance man, Theo, convincing them to
take spider-serum variants, transforming them into Arachne,
Antro, and Therak, respectively. The Manipulator paid and
threatened Napier to keep silent while he took his three new
mutates, now Deathweb, to work for him. However, the Manipulator
had altered the spider serum with which they were injected such
that they would require periodic treatments with an antidote or
they would die.

(Avengers West Coast#82) - Antro teleported
Deathweb into a wooded area in Avengers Compound, from which they
observed Spider-Woman before teleporting away again.

(Avengers West Coast#84 (fb) - BTS/86(fb) - BTS)
- Allegedly, Liberty party vice-presidential candidate Wilson
Lambert hired Deathweb to assassinate his running mate, Michael
Galvin, so that he could take his place and gain his supporters
as presidential candidate.

(Avengers West Coast#85) - Deathweb held their
own against the Avengers, but eventually grabbed Rachel Carpenter
and teleport away with her. Spider-Woman (followed by Spider-Man)
tracked down Mike Clemson to seek the Commission on Superhuman
Affairs' support. However, the Manipulator appeared, along with
Deathweb (with Rachel hidden away somewhere), and demanded that
Spider-Woman slay Spider-Man, or Arachne would kill Rachel.

(Avengers West Coast#86) - Deathweb and the
Manipulator teleported out of Clemson's base as it exploded
during the fight between Spider-Man and Spider-Woman, after which
Deathweb teleported into Avengers Compund and left a telemodule
through which the Manipulator revealed that he had Rachel and
tried to use her to keep the Avengers away from Galvan and
Lambert. However, Spider-Man and Spider-Woman survived the
explosion, too, and used a Spider-Tracer to track down and rescue
Rachel. Deathweb managed to ambush and kill Galvan before the
Avengers could stop them, but they were then defeated and
captured by the Avengers. Lambert took up Galvan's platform and
then denounced Deathweb, but Arachne stated that they had been
working for Lambert, causing him to lose all of his supporters.

(Spider-Woman II#1) - Deathweb slew Carter
Napier, then Therak followed him to ambush Spider-Woman and her
daughter and parents. Spider-Woman narrowly managed to fight off
Therak.

(Spider-Woman II#2 - BTS) - Spider-Woman sent
her parents and daughter into the Amazon rainforest to hide out
from Deathweb. However, after learning Deathweb's origins from
Val Cooper, she realized she was sending them into a trap and
went after them.

(Spider-Woman II#3) - Deathweb and the
Manipulator ambushed and captured the Cornwalls and Rachel
Carpenter, threatening to kill Rachel unless the Carpenters led
them to certain plants which contained additional chemicals
sought by the Manipulator. Spider-Woman located them, but was
ultimately defeated and captured by Deathweb, who obtained the
rest of the plant samples they sought.

(Spider-Woman II#4) - The Manipulator tested
out his new serum on Spider-Woman before administering it to
Deathweb, who doubled in power. Spider-Woman eventually broke
free and joined with Clemson in locating Deathweb and the
Manipulator in their Silicon Valley base, where she pushed the
Deathweb, forcing them to exhaust themselves, as their bodies had
not yet had a chance to adjust to their new power levels. The
barely conscious Therak incapacitated the Manipulator, angered
over being used, as well as the constant threat of dying from the
antidote, etc.

(OHotMU 2006#3) - Deathweb were imprisoned, their powers reverted to normal levels and their poisonings were appearently cured.

(Iron Man Annual 1999 (fb) - BTS) - Count
Nefaria had Therak broken out of jail and brought to his Sicilian Base,
where he would periodically drain his ionic power to refuel his
own.

ARACHNOID (Zoltan) - Acquired
powers similar to Spider-Man, framed the hero for crimes,
further mutated into half-spider form, fought Spider-Man and
others, lost powers. (TV) --Spider-Man and His
Amazing Friends: "Attack of the Arachnoid"

Hashi Noto. A Japanese
former graduate student, he was one of those assembled by Val
Cooper to form superhuman agents. He was honored to serve in the
group and equally happy to take a large payment and receive
powers. His power brought about the defeat of Deathweb at the
hands of the Avengers, when the Scarlet Witch managed to alter
his energies so that he teleported the group exactly where she
wanted, and the Avengers ambushed them.

His power was seemingly
based on the "trapdoor" spider, as he could teleport
himself and others. He could teleport groups of people at a time,
and make jumps over large or small distances, generally with
rapid frequency, though he could be exhausted by overusing his
power. His teleportation power caused him pain, which was
palliated by a suit of armor, which also allowed him to fire
various types of venom blasts (usually an acid spray) from its
"mandibles."

Dr. Sylvie Yacqua. Born a
Pacqui Indian, in Peru, she was one of those assembled by Val
Cooper to form superhuman agents. She also was happy to take the
payment to become a superhuman agent. She performed most of the
actual murders of the group.

She could fire both physical
and psychic webs from her wrists, though she wore special
gauntlets to ease the pain from doing so. She could extend a
spike from her gauntlets which was covered in a potent form of
spider venom, which was generally fatal within seconds.

Theodore "Theo" Davros. The former maintenance man in the
building in which Spider-Woman was empowered, his lack of
intelligence, experience, and generally creepy disposition didn't
stop the others from agreeing to use him as their test subject,
and he became the most powerful of the group. At some point after
their defeat, he became a prisoner of Count Nefaria, who used his
ionic powers to refuel his own from his base in Sicily.

Therak was-about eight feet tall, with six
arms, 6-8 eyes, and generally a hairy, spider-like appearance.
His powers were ionically based, and he had great superhuman
strength (Class 100?, enough to overpower Wonder Man) and
durability. After being amplified by the Manipulator, he grew to
15' tall, though it is not completely clear whether his (or the
rest of the group's) powers remained at that amplified level.

(Iron Man Annual 1999 (fb) - BTS) - Count
Nefaria had Therak broken out of jail and brought to his Sicilian Base,
where he would periodically drain his ionic power to refuel his
own.
